Ronald W Ulster Park , NY December 19, 2017 Appliance: Whirlpool Undercounter Dishwasher GU1200XTLT1 Whirlpool Dishwasher Gu1200xtlt1: Washing portion of dishwasher not and leaking before it stopped working. How to replace Water Inlet Kit. On our Whirlpool dishwasher when in the was mode the pump / motor started to make a lot of noise than after a while it started to leak majorly... All other functions worked.... So we figured it had to be the motor pump assembly... Watch the how to video than decided we could fix it with very little problems.. The replacement parts was a little high in cost but cheaper than a new dishwasher so we ordered the pump / motor.... With the help of the how to video we was able to replace the part with very little problems... One thing the video did not show was a extra part needed to be removed before the pump could be removed.. Once we figured it out the rest was one two three it was done... It now works like new.....
